Association of Dual Mycorrhizal Species with Leucas Aspera Enhances Growth and Total Biomass

Leucas aspera is a common weed known as “Thumbai “,is a widly distributed throughout India and is used in various fields of medicine and agriculture. There have a few studies conducted on the effects of co-inoculated of AM fungi in various crop plants for their better inoculation responses.The present study was carried out to investigate the effect of dual inoculation og different species of AM fungi Aculospora lacunose and Glomus mossae for enhancement of growth parameters and plant biomass. Significant increase over control in plant height ,number of leaves ,internode length, fresh and dry weight , stomatal index , leaf area index, chlorophyll content ,percent root colonization and spore count re recorded . The result confirms the feasibility of utilizing this strategy for their systematic cultivation and provides useful information for management agricultural systems.
